Mailchimp Automatic profile sync

As I know, the s2M itself puts the member in the corrrect list, but only the basic info, email and names and moves members to another list, when needed, say when member moves to another level with another list. It also deletes the member from the list, when the member closes the account with your site. But s2M won’t update the list, if the member changes his info. You may need “KC s2M+MC” plugin to do that. There is a free version in WP repository too.

Check that out. I use it and i LOVE it.
